Abstract
The utility model discloses a novel bearing comprising a bearing body and a shaft hole formed in the bearing body, wherein the shaft hole is a quincunxes-shaped inner hole, and a clearance is remained between a quincunxes petal and a shaft core. The bearing disclosed by the utility model has the advantages that the friction area between a shaft and the bearing is reduced, the oil content rate is high, oil can be stored, the service life is long, and the like.
Description
Technical field
The utility model relates to bearing, particularly relates to the novel bearing that a kind of middle-size and small-size radiation fan is used.
Background technique
Existing powder metallurgy oil-impregnated bearing, oil product is in the pore of metallurgical bearing, and oil content 10～25% does not wait, fixed with the structural parameter of design.And oil content is direct and life-span bearing is proportional.Relative is oil storage and guarantor's oil in addition.As following table illustrates relation:
| Project | Bearing structure | System architecture |
| Oil content | Exist | Do not exist |
| Oil-bearing structure | Exist | Exist |
| Protect oily structure | Do not exist | Exist |
On bearing life, in the impact of oil mass mode, be the number of oil content, the number of oil reserve on structure.
On traditional bearing, the friction of axle and bearing is the biggest factor in life-span.But keep away unavoidable.The life-span of bearing and oil mass and friction have direct relation.
The powder metallurgy oil-impregnated bearing of existing tradition, dried up and the life-span of termination bearing by rubbing to oil product of axle and bearing.The friction area of axle and bearing is larger, and the oil of consumption is just more.
The model utility content
The friction area that the utility model purpose is to provide a kind of axle and bearing reduces, oil content is high, can oil storage, the novel bearing of long service life.
To achieve these goals, the utility model is designed a kind of novel bearing, comprises bearing body and is arranged on the axis hole on bearing body, and described axis hole is the blossom type endoporus, between plum blossom lobe and axle core, leaves gap.
Described axis hole is provided with two plum blossom lobes or some plum blossom lobes.
Preferred scheme: described axis hole is provided with four plum blossom lobes.
The internal diameter of described axis hole is 0.5～8mm.
Described bearing is powder metallurgy oil-impregnated bearing.
This bearing structure of the utility model bearing, have the function of oil storage, reduced 30%～50% pivot friction area of conventional construction.Increase the life-span of bearing, reduced the noise of the friction of bearing.
the accompanying drawing explanation:
Fig. 1 is the plan view of the utility model bearing;
Fig. 2 is the plan view of the utility model bearing with axle;
Fig. 3 is the sectional structure schematic diagram of AA direction in Fig. 2;
Fig. 4 is the perspective view of the utility model bearing with axle.
Embodiment
For the ease of those skilled in the art's understanding, below in conjunction with specific embodiment and accompanying drawing, structural principle of the present utility model is described in further detail:
As shown in Figure 1 to 4, a kind of novel bearing, it comprises bearing body 1 and is arranged on the axis hole 3 on bearing body 1, described axis hole 3 is the blossom type endoporus, between plum blossom lobe 4 and axle core 5, leaves gap 6.
As shown in Figure 1, Figure 2 and Figure 4, described axis hole 3 is provided with four plum blossom lobes 4.Axis hole 3 also can be provided with two plum blossom lobes 4 or some plum blossom lobes 4.This can be regulated according to the actual needs, and the space of plum blossom lobe 4 forms the gap 6 of axle and bearing, can oil storage in gap 6, and make the oil content in axis hole high, the activity of axle increases flexible, increases the service life.
As shown in Figure 1, Figure 2 and Figure 4, the internal diameter of the described axis hole 3 of the utility model bearing is 0.5～8mm.
The utility model bearing is powder metallurgy oil-impregnated bearing.
Gap-Ratios traditional bearing between the bearing body of the utility model bearing and axle core is large many.Can store the oil mass that is equivalent to the oil content of bearing own from here.Size with the different oil masses of design parameter there will be variation.Described novel aspect oil mass, comparable traditional design increases by 20%～100% and does not wait.
The utility model bearing has following improvement:
| Project | Conventional construction | New structure | Comparison result |
| Noise | Area of contact is 100% | Area of contact is 30%～90% | Noise reduces relatively, improves product quality and life-span |
| Oil storage | The bearing oil storage is 0 | Oil storage is that 20%～100% of oil content does not wait | Oil mass increases, and the life-span also increases simultaneously |
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not to the restriction of the utility model protection domain; although with reference to preferred embodiment, the utility model has been done to explain; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement the technical solution of the utility model, and not break away from essence and the scope of technical solutions of the utility model.
